Question

Simplify and write the answer with positive exponents.
A) (5^-1 devided by 3^-1)^2

Answer 1

Answer:

5²/3²

Step-by-step explanation:

(5-¹ ÷ 3-¹ )²

= 5-¹ can be written as 5/1

= 3-¹ can be written as 3/1

so 5/1 ÷ 3/1 = Reciprocal = 5/1 × 1/3 = 5/3.

now (5/3)² = 5×5 / 3×3

= 25/9

= 5²/3²
